Currently, ice_stat_update32 and ice_stat_update40 will limit the
value of the software statistic to 32 or 40 bits wide, depending on
which register is being read.
This means that if a driver is running for a long time, the displayed
software register values will roll over to zero at 40 bits or 32 bits.
This occurs because the functions directly assign the difference between
the previous value and current value of the hardware statistic.
Instead, add this value to the current software statistic, and then
update the previous value.
In this way, each time ice_stat_update40 or ice_stat_update32 are
called, they will increment the software tracking value by the
difference of the hardware register from its last read. The software
tracking value will correctly count up until it overflows a u64.
The only requirement is that the ice_stat_update functions be called at
least once each time the hardware register overflows.
While we're fixing ice_stat_update40, modify it to use rd64 instead of
two calls to rd32. Additionally, drop the now unnecessary hireg
function parameter.

ice_parse_caps is used to parse both device and function capabilities.
Currently, capabilities are printed with a cryptic "HW caps" prefix,
which makes it difficult to distinguish whether the capabilities being
printed are device or function capabilities.
This patch makes a change to add a "func cap" prefix when printing
function capabilities, and a "dev cap" prefix when printing device
capabilities.
This patch also changes some of the capability print strings for
consistency.

This patch adds a new function ice_pf_dcb_cfg (and related helpers)
which applies the DCB configuration obtained from the firmware. As
part of this, VSIs/netdevs are updated with traffic class information.
This patch requires a bit of a refactor of existing code.
1. For a MIB change event, the associated VSI is closed and brought up
again. The gap between closing and opening the VSI can cause a race
condition. Fix this by grabbing the rtnl_lock prior to closing the
VSI and then only free it after re-opening the VSI during a MIB
change event.
2. ice_sched_query_elem is used in ice_sched.c and with this patch, in
ice_dcb.c as well. However, ice_dcb.c is not built when CONFIG_DCB is
unset. This results in namespace warnings (ice_sched.o: Externally
defined symbols with no external references) when CONFIG_DCB is unset.
To avoid this move ice_sched_query_elem from ice_sched.c to
ice_common.c.

When the physical link goes up or down, the driver is supposed to
receive a link status event (LSE). The driver currently has the code
to handle LSEs but there is no firmware support for this feature yet.
So this patch adds the ability for the driver to poll for link status
changes. The polling itself is done in ice_watchdog_subtask.
For namespace cleanliness, this patch also removes code that handles
LSE. This code will be reintroduced once the feature is officially
supported.

This patch implements parts of ice_sriov_configure and VF reset flow.
To create virtual functions (VFs), the user sets a value in num_vfs
through sysfs. This results in the kernel calling the handler for
.sriov_configure which is ice_sriov_configure.
VF setup first starts with a VF reset, followed by allocation of the VF
VSI using ice_vf_vsi_setup. Once the VF setup is complete a state bit
ICE_VF_STATE_INIT is set in the vf->states bitmap to indicate that
the VF is ready to go.
Also for VF reset to go into effect, it's necessary to issue a disable
queue command (ice_aqc_opc_dis_txqs). So this patch updates multiple
functions in the disable queue flow to take additional parameters that
distinguish if queues are being disabled due to VF reset.

Currently there is no support for dynamic interrupt moderation. This
patch adds some initial code to support this. The following changes
were made:
1. Currently we are using multiple members to store the interrupt
granularity (itr_gran_25/50/100/200). This is not necessary because
we can query the device to determine what the interrupt granularity
should be set to, done by a new function ice_get_itr_intrl_gran.
2. Added intrl to ice_q_vector structure to support interrupt rate
limiting.
3. Added the function ice_intrl_usecs_to_reg for converting to a value
in usecs that the device understands.
4. Added call to write to the GLINT_RATE register. Disable intrl by
default for now.
5. Changed rx/tx_itr_setting to itr_setting because having both seems
redundant because a ring is either Tx or Rx.
6. Initialize itr_setting for both Tx/Rx rings in ice_vsi_alloc_rings()

Currently, switch filters get replayed after reset. In addition to
filters, other VSI attributes (like RSS configuration, Tx scheduler
configuration, etc.) also need to be replayed after reset.
Thus, instead of replaying based on functional blocks (i.e. replay
all filters for all VSIs, followed by RSS configuration replay for
all VSIs, and so on), it makes more sense to have the replay centered
around a VSI. In other words, replay all configurations for a VSI before
moving on to rebuilding the next VSI.
To that effect, this patch introduces a VSI replay framework in a new
function ice_vsi_replay_all. Currently it only replays switch filters,
but it will be expanded in the future to replay additional VSI attributes.

The functions that are used for PF VSI/netdev setup will also be used
for SR-IOV support. To allow reuse of these functions, move these
functions out of ice_main.c to ice_common.c/ice_lib.c
This move is done across multiple patches. Each patch moves a few
functions and may have minor adjustments. For example, a function that was
previously static in ice_main.c will be made non-static temporarily in
its new location to allow the driver to build cleanly. These adjustments
will be removed in subsequent patches where more code is moved out of
ice_main.c
In this particular patch, the following functions were moved out of
ice_main.c:
int ice_add_mac_to_list
ice_free_fltr_list
ice_stat_update40
ice_stat_update32
ice_update_eth_stats

This patch refactors aspects of the VSI allocation, deletion and rebuild
flow. Some of the more noteworthy changes are described below.
1) On reset, all switch filters applied in the hardware are lost. In
the rebuild flow, only MAC and broadcast filters are being restored.
Instead, use a new function ice_replay_all_fltr to restore all the
filters that were previously added. To do this, remove calls to
ice_remove_vsi_fltr to prevent cleaning out the internal bookkeeping
structures that ice_replay_all_fltr uses to replay filters.
2) Introduce a new state bit __ICE_PREPARED_FOR_RESET to distinguish the
PF that requested the reset (and consequently prepared for it) from
the rest of the PFs. These other PFs will prepare for reset only
when they receive an interrupt from the firmware.
3) Use new functions ice_add_vsi and ice_free_vsi to create and destroy
VSIs respectively. These functions accept a handle to uniquely
identify a VSI. This same handle is required to rebuild the VSI post
reset. To prevent confusion, the existing ice_vsi_add was renamed to
ice_vsi_init.
4) Enhance ice_vsi_setup for the upcoming SR-IOV changes and expose a
new wrapper function ice_pf_vsi_setup to create PF VSIs. Rework the
error handling path in ice_setup_pf_sw.
5) Introduce a new function ice_vsi_release_all to release all PF VSIs.

This patch is an adaptation of the work originally done by Grishma
Kotecha <grishma.kotecha@intel.com> that in summary refactors the
switch filtering logic in the driver. More specifically,
- Update the recipe structure to also store list of rules
- Update the existing code for recipes like MAC, VLAN, ethtype etc to
use list head that is attached to switch recipe structure
- Add a common function to search for a rule entry and add a new rule
entry. Update the code to use this new function.
- Refactor the rem_handle_vsi_list function to simplify the logic
